The purpose of present study is to investigate the dynamic response of two conventional types of solid oxide fuel cells to the inlet air mass flow rate variation. A dynamic compartmental model based on CFD principles is developed for two typical planar and tubular SOFC designs. The model accounts for transport processes (heat and mass transfer), diffusion processes, electrochemical processes, a...

cellular manufacturing system (cms) is highly important in modern manufacturing methods. given the ever increasing market competition in terms of time and cost of manufacturing, we need models to decrease the cost and time of manufacturing. in this study, cms is considered in condition of dynamic demand in each period. the model is developed for facing dynamic demand that increases the cost of ...

BACKGROUND Low-dose combined spinal-epidural analgesia in labor has proved popular with women because lower-limb motor power is preserved, allowing ambulation. However, there has been debate about the safety of allowing women to walk following low-dose regional analgesia because of somatosensory impairment. The authors undertook a prospective controlled observational study using computerized dy...

The paper quantitatively evaluates the interaction between capital-skill complementarity and endogenous low-, medium-, and high-skilled labour supply in generating wage inequality, using a dynamic computable general equilibrium (CGE) model of the Auerbach-Kotliko¤ (1987) type. The counterfactual analysis conducted shows that the German skill premium de…ned by the 9 to 1 decile limit of earnings...

a r t i c l e i n f o JEL classification: E62 H22 O41 Keywords: Two-sector model Human capital Optimal factor tax incidence This paper studies the optimal factor tax incidence in a standard two-sector, human capital-based endoge-nous growth model elucidated by Lucas (1988). Capital income taxes generate dynamic inefficiency for capital accumulation and labor income taxes create dynamic ineffici...

The labor force participation of elderly people in the Netherlands is extremely low. In addition, the share of elderly people in the population will increase substantially in coming decades. This leads to two major concerns: the availability of sufficient and qualified labor, and the affordability of (social) benefit programs. This study provides insights in the determinants of elderly labor fo...

In this study, an attempt has been made to apply Learning Vector Quantization (LVQ) approach, one of the network types of Artificial Neural Networks (ANN), into worker assignment problems for VCMS environment and analyze the network performance and effectiveness under different cell configurations and time periods. Worker assignment problems assume a crucial role in any type of manufacturing sy...

From the mid-1950s through the mid1980s, migration between Mexico and the United States constituted a stable system whose contours were shaped by social and economic conditions well-theorized by prevailing models of migration. It evolved as a mostly circular movement of male workers going to a handful of U.S. states in response to changing conditions of labor supply and demand north and south o...

An extensive literature in labor economics recognizes that the life-cycle labor force participation of a woman is highly associated with her family choices. There is, however, virtually no study going further to incorporate female occupational choices. This paper attempts to fill this gap in labor supply literature by examining the interrelatedness of occupation, marital status and fertility ch...
